  1. Hello, I have to submit my topic and design for my biology extended essay by this Friday (tomorrow! ), and I have a topic and rough idea of what I would like to do, though I was wondering if I can get some advice and guidance for which way to take my experimenting. (an answer asap would be much appreciated ! ) So my topic is within the plant sciences and my research question is How does exposure to vibration and sound affect the growth rate of Raphanus sativus L.? *(Should I measure the growth rate, or the germination rate? would either be fine? and if they are, what would be the best way to carry out each?) So my plan so far is to place equal amount of seeds in 5 petri dishes and grow them in a controlled environment for five days for each trial. Each petri dish would have their own source of vibration (most likely from a cell phone, unless anyone has another idea ) placed at least 15.24 cm (6 inches away; all distances would be the same as it is a control) from the petri dish, and I would expose each petri dish (except for the control dish) to vibration for different lengths of time (ex: dish one- 2 hrs, dish two- 4 hrs etc) for five days. The same method would apply to the test with sound, only with a new set of seeds. The sound is a single pitch played continuously from the same distance, and is also played from a cell phone. How does that sound? Any suggestions or improvements? Any ideas for the aspect of analysis and things I should mention? Thank you in advanced !
